Title: Method for dephosphorizing molten iron
Inventor: MURAKAMI TOSHINORI
IPC: C21C1/02
Filed: 2001-11-20
Abstract: PROBLEM TO BE SOLVED: To provide a method capable of efficiently dephosphorizing molten iron at a low cost by the method which can use inexpensive dephosphorized flux (slag-based dephosphorizing flux) without using an expensive slag-making agent such as CaF2 , can secure a stable operability and can reduce iron loss in order to reduce the cost of a dephosphorization. SOLUTION: In this method for dephosphorizing the molten iron, before the dephosphorization, the molten iron is subjected to a desiliconization beforehand to remove the slag on the surface of the molten iron. When the molten iron is dephosphorized without using a material containing fluorine by a lance injection, the molten iron is dephosphorized so that the basicity of the slag after the dephosphorization is regulated to (CaO/SiO2 )=2.5-5.0, Al2 O3 =2-10 mass% and T.Fe>=2 mass% by using the dephosphorizing flux containing ingot- making slag.
